It is impossible to imagine the technological process of production of building materials, dry building mixes, reinforced concrete products without an important technological operation of transporting powder materials. Pneumatic chamber pumps are widely used for transporting powder bulk materials and are a mandatory element in the configuration of concrete plants and other mixing equipment. Their advantages are the possibility of full automation of work, reliable protection from atmospheric influences and the necessary sanitary and hygienic working conditions. Therefore, pneumatic chamber pumps are increasingly used for transportation. Compressed air is piped into the pump chamber. The bulk material is saturated with air, the resulting aerated mixture under the influence of excess pressure enters the pipeline and is transported in the specified direction. The disadvantage of pneumatic chamber pumps is the increased consumption of compressed air during transportation. To reduce air consumption, various aeration devices are used. Currently, at the modeling stage, modern software is used to determine the effectiveness of the developed aeration device. The influence of the air flow velocity on the discharge of a pneumatic chamber pump is considered. A design solution for the aeration device of the TA-29 pneumatic chamber pump is proposed.
